Abstract
Pine needle-induced abortion in cattle is a serious problem in many areas of western United States and Canada. Field observations on pine needle abortion indicate that this condition is stress related. The results of this research indicate that the pine needle-induced abortion occurs much more readily if cows are under stress.
摘要
在美国西部和加拿大的许多地区，松针导致的牛流产是一个严重问题。对松针流产的实地观察表明，这种情况与应激有关。本研究结果表明，如果母牛处于应激状态，松针导致的流产更容易发生。
